Suffolk Stag Beetle Survey

Flickr Search

The Stag Beetle (Lucanus cervus) is Britain’s largest beetle, and Suffolk is one of its strongholds. Adults are most often seen in late spring and early summer, flying at dusk or wandering on the ground in search of mates. The species is under pressure from the loss of dead and decaying wood, the habitat its larvae depend on for up to seven years underground before emerging as adults. Recording your sightings helps us map where Stag Beetles are occurring across the county, identify areas where they are doing well, and make the case for protecting the habitats they need.
